General Maintenance and Diagnostic Data

Fine Tuning-LS (Low Speed)

This parameter sets the percentage of the Typical
Max Speed below which the "LS" parameters will be
used.

Fine Tuning-Reversal Soften

This parameter, when set to larger values create a
softer reversal from regen braking to drive when near
zero speed. The parameter will soften the transition
when the regen and drive current limits are set to dif-
ferent values.

Fine Tuning-Max Speed Accel

In some applications, the Max Speed value is
changed frequently over the CANbus. The Max
Speed Accel parameter controls the rate at which the
maximum speed setpoint is allowed to change when
the value of Max Speed is raised. The rate set by this
parameter is the time to ramp from 0 RPM to Typical
Max Speed RPM. If Max Speed is raised from 1000
RPM to 3000 RPM, the Typical Max Speed is 3200
RPM and the rate is 10.0 seconds, it will take 10.0 *
(3000–1000) / 3200 = 6.25 seconds to ramp from
1000 RPM to 3000 RPM.

Fine Tuning-Max Speed Decel

This parameter is like the Max Speed Accel parame-
ter, except that it controls the rate at which the maxi-
mum speed setpoint is allowed to change when the
value of Max Speed is lowered. If one changes Max
Speed from 300 RPM to 1500 RPM, the Typical Max
Speed is 3200 RPM, and the rate is 5.0 seconds, it
will take 5.0 * (3000–1500) / 3200 = 2.34 seconds to
ramp from 3000 RPM to 1500 RPM.

Interlock Timeout

This parameter will set the time for which the truck
can remain at idle condition while the arm is in opera-
tional region B. See Figure 9030-03-3.

Mode (1 through 3) -Max Speed

This parameter defines the maximum requested mo-
tor rpm at full throttle.
RPM = V * 936
Desired
Example: RPM = 2.5MPH * 936 = 2340 rpm

Mode (1 through 3) -Max Accel

This parameter sets the rate (in seconds) at which the
motor speed command increases when throttle is ap-
plied. Larger values represent slower response.

Mode (1 through 3) -Walk Accel

This parameter sets the rate (in seconds) at which the
motor speed command increases when throttle is ap-
plied, when truck is not in turtle mode. Larger values
represent slower response.

Mode (1 through 3) -Max Decel

This parameter sets the rate (in seconds) that is used
to slow down the vehicle when the throttle is reduced.
Larger values represent slower response.

Mode (1 through 3) -Neutral Braking

This parameter adjusts how neutral braking occurs
progressively when the throttle is reduced toward the
neutral position or when no direction is selected.

Mode (1 through 3) -Max Braking

This parameter sets the rate (in seconds) at which the
vehicle slows down when full brake is applied or when
throttle is applied in the opposite direction.

Max Speed TM2

This parameter defines the maximum requested mo-
tor rpm at full throttle when the truck is driven in Ad-
vance Turtle mode in region B. See Figure 9030-03-3.

Max Accel TM2

This parameter sets the rate (in seconds) at which the
motor speed command increases when throttle is ap-
plied. This parameter is applicable only while the truck
is driven while in Advance Turtle Mode. Larger values
represent slower response.

Max Decel TM2

This parameter sets the rate (in seconds) that is used
to slow down the vehicle when the throttle is reduced.
Larger values represent slower response.
